by removing the center crossmembers skid plate and removing the lower transmission mount screws I got plenty of space to remove the rear most transmission pan screws, I was able to use both a 10mm 1/4 inch flex head and a 3/8 flex head, and I had space to use my airtools; I learned not to jack it up to high cause if you do, the mount bolts will and go off center, tough to get back into mount holes but I got it, next time, I will leave them in place slightly threaded; next, will be adding 1.75 gallons of fluid, thats what it took last time to fill!! sound about right???
